Reminder!! Please help. ------------------------------- Hi, Is there some kind of script that I can run to know the exact issue about what resource crunch is there ?
Below is the memory and disk utilization of controller: [heat-admin@overcloud-controller-0 ~]$ free -m total used free shared buff/cache available Mem: 128722 25632 92042 70 11047 102377 Swap: 0 0 0 [heat-admin@overcloud-controller-0 ~]$ df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 63G 0 63G 0% /dev tmpfs 63G 39M 63G 1% /dev/shm tmpfs 63G 27M 63G 1% /run tmpfs 63G 0 63G 0% /sys/fs/cgroup /dev/sda2 1.9T 12G 1.9T 1% / tmpfs 13G 0 13G 0% /run/user/0 tmpfs 13G 0 13G 0% /run/user/1000 Same memory and disk available on all three controllers. On the same environment when I installed overcloud with redhat repos and redhat overcloud images...I have not faced this issue. I have tested almost 500 projects and 500 networks (one network per project) on the same environment with redhat and it was working fine without any issue and cluster failure. But when I am using Centos-7 tripleo repo's its happening again n again.

Rahul - there is nothing relevant in the attached file, you've probably executed LogTool on "working environment", so there is nothing interesting in it. I think that you had to mention the Error we've detected in an already "crushed" environment, just as I was suggesting you to do. Yes, nothing interesting in the attached logs. <blockquote> Alfredo - this Error was logged almost on each OC node at the same time when the problems had started. * hyp-0 * ------------------------------ LogPath: /var/log/containers/neutron/openvswitch-agent.log.1 ------------------------------ * IsTracebackBlock:False * UniqueCounter:1 * AnalyzedBlockLinesSize:18 * 26712-2020-07-21 20:07:54.604 54410 INFO neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [req-a2173b45-f18b-45f9-90d8-cb8ab1754332 - -...<--LogTool-LINE IS TOO LONG! * 26713-2020-07-21 20:07:54.605 54410 INFO neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [req-a2173b45-f18b-45f9-90d8-cb8ab1754332 - -...<--LogTool-LINE IS TOO LONG! * 26714:2020-07-21 20:07:56.363 54410 ERROR oslo.messaging._drivers.impl_rabbit [-] [2f214f0b-84d0-49d4-bcf4-477565903585] AMQP server overcloud-control...<--LogTool-LINE IS TOO LONG! * 26715:2020-07-21 20:07:56.364 54410 ERROR oslo.messaging._drivers.impl_rabbit [-] [664475bc-3b39-4ce5-a60e-f010b8d5201d] AMQP server overcloud-control...<--LogTool-LINE IS TOO LONG! * 26716:2020-07-21 20:07:56.364 54410 ERROR oslo.messaging._drivers.impl_rabbit [-] [68a0ab43-a216-43fe-aa58-860d3dc5e69e] AMQP server overcloud-control...<--LogTool-LINE IS TOO LONG! * ... * ... * ... * LogTool --> THIS BLOCK IS TOO LONG! * LogTool --> POTENTIAL BLOCK'S ISSUES: * 26714:2020-07-21 20:07:56.363 54410 ERROR oslo.messaging._drivers.impl_ rabbit [-] [2f214f0b-84d0-49d4-bcf4- 477565903585] AMQP server overcloud-controller-2.inter.. . * ection.

AFAIK, there is not a configuration that may limit the number of networks or project, but it may be hitting some resources scarcity that affect the running services. What's the memory sizing and usage of the controllers? <blockquote> You can find more Error Blocks in the attached file. Thanks! </blockquote>
